Cov ntaub ntawv hlau uas siv rau hauv kev tsim kho, kev tsim tshuab, thiab lwm yam teb suav nrog H-zoo li hlau, lub kaum sab xis hlau, thiab U-channel hlau

H BEAM: Ib hom hlau uas zoo li tus I uas muaj cov flange sab hauv thiab sab nraud sib luag. Cov hlau uas zoo li tus H muaj xws li cov hlau dav dav H (HW), cov hlau nruab nrab H (HM), cov hlau nqaim H (HN), cov hlau nyias nyias H (HT), thiab cov hlau H (HU). Nws muaj zog khoov thiab nias tau zoo thiab yog hom hlau uas siv dav tshaj plaws hauv cov qauv hlau niaj hnub no.

Lub kaum sab xis hlau, tseem hu ua hlau kaum sab xis, yog cov khoom siv hlau uas muaj ob sab ntawm cov ces kaum sab xis. Nws yog pawg ua cov hlau kaum sab xis sib npaug lossis cov hlau kaum sab xis tsis sib npaug. Cov lus qhia tshwj xeeb yog qhia los ntawm qhov ntev thiab tuab ntawm sab, thiab tus lej qauv yog raws li qhov ntev hauv centimeters. Cov hlau kaum sab xis sib npaug yog txij li qhov loj me 2 txog 20, thaum cov hlau kaum sab xis tsis sib npaug yog txij li qhov loj me 3.2/2 txog qhov loj me 20/12.5. Cov hlau kaum sab xis muaj cov qauv yooj yim thiab yooj yim rau kev teeb tsa, ua rau nws siv dav hauv cov qauv hlau sib dua, cov khoom siv txhawb nqa, thiab lwm yam kev siv.

U-channel hlauyog ib daim hlau zoo li tus U. Nws cov lus qhia tau qhia ua millimeters li qhov siab ntawm lub hauv paus (h) × qhov dav ntawm ceg (b) × qhov tuab ntawm lub hauv paus (d). Piv txwv li, 120 × 53 × 5 qhia txog ib txoj kab uas muaj qhov siab ntawm lub hauv paus ntawm 120 mm, qhov dav ntawm ceg ntawm 53 mm, thiab qhov tuab ntawm lub hauv paus ntawm 5 mm, tseem hu ua 12 # channel steel. Channel steel muaj kev tiv thaiv kev khoov zoo thiab feem ntau siv rau kev txhawb nqa cov qauv thiab hauv cov cheeb tsam uas muaj peev xwm thauj khoom siab.
